Abstract: The present disclosure provides a composite material. The composite material includes 20 to 40 weight percent (wt. %) of a polymerizable component; 6 to 40 wt. % of ceramic fibers; and 30 to 70 wt. % of nanoclusters. Each of the ceramic fibers has a diameter and a length, the ceramic fibers having an arithmetic mean diameter of 0.3 micrometers to 5 micrometers, and the length of fifty percent of the ceramic fibers (based on a total number of the ceramic fibers) is at least 10 micrometers and the length of ninety percent of the ceramic fibers is no greater than 500 micrometers. The present disclosure also provides a method of making the composite material. The method includes obtaining components and admixing the components to form a composite material. Further, the present disclosure provides a method of using a composite material including placing a composite material near or on a tooth surface, changing the shape of the composite material near or on a tooth surface, and hardening the composite material. In addition, the present disclosure provides dental products and kits. Hardened composite materials can exhibit high strength.

Abstract: A method of making a porous metal matrix composite is provided. The method includes mixing a metal powder, a plurality of inorganic particles, and a plurality of discontinuous fibers to form a mixture, wherein the metal powder comprises aluminum, magnesium, an aluminum alloy, or a magnesium alloy. The method further includes sintering the mixture to form the porous metal matrix composite. Typically, the inorganic particles comprise porous particles or ceramic bubbles or glass bubbles, and the inorganic particles and the discontinuous fibers are dispersed in the metal. The metal matrix composite has a lower density than the metal and an acceptable yield strength.

Abstract: A metal matrix composite is provided, including a metal, inorganic particles, and discontinuous fibers. The inorganic particles and the discontinuous fibers are dispersed in the metal. The metal includes aluminum, magnesium, or alloys thereof. The inorganic particles have an envelope density that is at least 30% less than a density of the metal. The metal matrix composite has a lower envelope density than the matrix metal while retaining a substantial amount of the mechanical properties of the metal.
